| Abstract |
|
Critical fusion frequency (CFF) of toad rods was examined at various intensities using intracellular recordings. Data were compared to CFF measurements (as a function of intensity) obtained with the electroretinogram (ERG) and with a horizontal cell. In all instances the rod (and rod mediated) responses produced a curve which increased monotonically to a high frequency asymptote at about 6 Hz. The curves obtained with the ERG and the horizontal cell were double branched. The upper branch exhibited a Purkinje shift and thus must have been produced by cones. Even when using a red background to suppress cone sensitivity, there was no sign of a second rod mediated branch in the CFF curves from this retina.
